Title: Electrical multiple plug socket
Inventor: STEFANSKI MANFRED ING GRAD
IPC: H01R25/00
Filed: 1982-05-06
Abstract: The invention relates to an electrical multiple plug socket having an elongated insulating material base for holding contact parts and connecting parts, which in each case consist of two spring strips (11, 12), which are placed adjacent to one another and run in the base longitudinal direction, and have a plurality of contact sockets (16), which are arranged one behind the other, are formed by means of contact socket halves (which are stamped into the spring strips in the form of radii) and supplement one another after the assembly of two spring strips into a spring strip pair to form complete contact sockets (16). In the case of such spring strips, it is intended that the contact pressure should not be transferred by supporting the spring strips on the insulating material base. The invention creates a self-supporting version of the spring strip pairs, in which the spring strips are mutually supported. For this purpose, indentations (22) are provided in the spring strips (11, 12), which indentations (22) extend approximately to the centre on the left and right, adjacent to the contact sockets (16), and by means of which two spring strips (11, 12) can be plugged together to form a bracketed spring strip pair. <IMAGE>

Title: Method and arrangement for operating convertor-fed rotary current drives for vehicles
Inventor: HAHN KARL DIPL ING
IPC: B60L3/10
Filed: 1982-11-27
Abstract: The invention is concerned with a method for operating inverter-fed rotary current drives for vehicles, in particular for railways, in which during normal operation the rotor frequency of the rotary current asynchronous motor is made to follow its rotational frequency for the purpose of keeping constant a predetermined torque and overspeed or slip processes are compensated by means of the actual vehicle speed, under the influence of the engine characteristic line Md = F(n). The extreme steepness of the natural characteristic line of the asynchronous motor leads to troublesome dynamic processes when the rotor frequency is being fixed. In order to overcome this disadvantage and to make the steepness of the torque/engine speed characteristic line of the rotary current asynchronous motor capable of being matched to the requirements of optimum slip and overspeed protection by means of circuitry:   - in each case the difference is formed between the rotational frequency (frot) of the rotary current asynchronous motor and a frequency (fv) assigned to the actual vehicle speed - this frequency difference is reduced by a factor (k) in accordance with a desired flattening of the motor characteristic line and - the reduced frequency difference (1/k . frot-fv) is added to the rotor frequency, formed from the rotational frequency (frot) and set slip frequency (fsset), for the rotary current asynchronous motor depending on whether it is a case of travel mode or braking mode, with the correct sign with the effect of reducing the motor slip frequency.   <IMAGE>

Title: Method and equipment for the controlled irrigation of plant crops
Inventor: MEYNS REINER
IPC: A01G31/00
Filed: 1983-09-01
Abstract: In the controlled irrigation of earth-free plant crops (hydroponics) by means of fertiliser solutions of at least one fertiliser component dissolved in a particular type of water (well water, rainwater), pH and electrical conductivity are determined. The fertiliser solution composition is adjusted to the intended value with the aid of the actual value determined. Correspondingly, the concentration is changed to the desired fertiliser solution composition. In order to ensure individual, rapid adjustment to different crop cycles corresponding in each case to different fertiliser compositions, a separate actual value determination of the individual fertiliser solution is carried out successively at a central station for each of the various crop cycles, and a concentration change in the fertiliser solution is effected by individually metered addition of fertiliser components and/or types of water.

Patent DE-3338765-A1 (DE)
Inventor: KRANITZKY WALTER DR
IPC: G06T15/00
Filed: 1983-10-26
Abstract: A method and apparatus for representing a processed workpiece in perspective with invisible covered edges on the picture screen of a numerically controlled machine tool includes the steps of resolving both the workpiece and the tool into equidistant sections and storing the coordinates of these sections in a RAM. In correspondence to the relative movements of the tool and workpiece determined by the numerical control program, the associated sections of the tool and workpiece are superimposed in an image point memory. With the aid of a simple algorithm the section contour of the workpiece is altered by the superposition is determined, and its coordinates are stored in the RAM. After this process has been completed for all section planes, all sections are successively fed into the image point memory, with succeeding sections offset by several image points in the X and Z directions with respect to the preceding sections. After each superposition, the algorithm is used to determine the resulting outer contour, which is applied to the display. Covered parts of sections lying in the background are not represented on the display, since they lie inside the outer contour determined up to that time.
